Huge vintage Navajo sterling silver cuff bracelet. It is set with a large turquoise stone that is natural with a light polish. It is in two shades of green and has chocolate brown chert matrix. I won't speculate on what mine produced this because when I see this olive green color, it may have been blue at one time and changed with exposure and wear. 

Stone measures 1 3/8" by 1 1/8". It has a very rough bezel that is doubled up with a hand-notched shape over a second solid layer. Very simple design with wire work.

Interior measures 5 1/8" plus the opening of 1 1/4". 2" wide at center front. 44.8 grams
